The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

You chose a number greater than 10 for an accelerator key.
QBX only accepts accelerator key numbers ranging from
2 to 10. Alt+F1 is reserved for the help system.
 
Try typing a number between 2 and 10 in the box after the
statement, "Accelerator Key: Alt+F".
